WINDOW CONSTRUCTION Filed Jan. 19, 1953 United States PatentO 2,726,395 wnsuow CONSTRUCTION Marshall N. Anderson, Gfayslake, Ill., assignor to Sellstrom Manufacturing Co., Chicago, lll., a corporation of Illinois Application January 19, 1953, Serial No. 332,002 2 Claims. (c1. 24

Thus it is one of the objects of this invention to provide a window construction wherein the panels forming a part thereof are readily removable for cleaning or replacement purposes.

It is a further object of this invention to provide a window construction wherein light rays are only permitted to pass through the panels forming a part thereof.

It is a still further object of this invention to provide a window construction which is of simple, yet sturdy design, and is inexpensive to make.

Further and additional objects will appear from the description, accompanying drawings, and appended claims.

In accordance with one embodiment of this invention, a window construction is provided comprising a frame member having a slotted side portion and apertured front and back sections arranged in spaced substantially parallel relation wherein the apertures thereof are substantially coincident to one another, a pair of removable panels insertable through said slotted side portion for registration with said section apertures, and a spacer element having a first portion insertable through said slotted side portion for disposition intermediate said panels to effect retentionof said panels in spaced relation with respect to one another and in engagement with said apertured front and back sections.

For a more complete understanding of this invention reference should be made to the drawings wherein:

Figure 1 is a perspective view of the improved window construction assembled with the spacer element and one lens thereof partially withdrawn from the frame member;

Fig. 2 is an enlarged front view of the improved window construction assembled and with portions of the frame member thereof cut away;

Fig. 3 is a right end view of the window construction, shown in Fig. 2;

Fig. 4 is a sectional view taken along line 44 of Fig. 2;

Fig. 5 is a sectional view taken along line 5-5 of Fig. 2; and

Fig. 6 is an enlarged perspective view of the spacerelement alone.

Referring now to the drawings and more particularly to Fig. 1, a window construction 10 is shown which, in this instance, is adapted for use in combination with the protective mask of a welders helmet, not shown.

The window construction 10 comprises a frame member 11 having apertured front and back sections 12 and 13,

2,726,395 Patented Dec. 13, 1955 2 1 respectively, which arearranged in spaced parallel relation'so that the apertures 14 formed in the sections are in coincident relation. The frame member 11 in this instance'is rectangular in shape. One of the narrow sides 15 of the'frame member 11 is provided with an elongated slo t'16which is substantially coincident with the full extent of the side 15. The slot 16 is provided to enable a pair of lenses or panels 17 and 18 to be inserted between sections 12 and13 and into registered or overlyingrelation with respect to apertures 14. The panels 17 and 18 are of substantially the same shape and, in turn, are of substantially the same shape as apertures 14 but slightly larger than the latter so that the marginal edge 20 of the panels rest against the front and back sections. The panel 17, which engages the front section 12 of the frame member 11, is constructed preferably of-a clear transparent inexpensive plastic material. The panel 17 is adapted to function as a protective shield for panel 18. This latter panel 18 is constructed of 'a smoked glass material and is adapted to shield out harmful light rays such as those created during a welding operation. The panel 18 is adapted to rest against back section 13, as seen in Fig. 5. To prevent panel 18 from becoming scratched or chipped by the frame member, a gasket 21, formed of felt or some other suitable material, is positioned intermediate panel 18 and back section 13. The gasket 21 is rectangular in shape and has an aperture 22 of the same configuration as the apertures 14 formed in sections 12 and 13.

To retain the panels 17 and 18 in spaced relation, when they are assembled within the frame member, a spacer element 23 is provided as seen more clearly in Fig. 6. Element 23 is formed of a resilient, preferably metallic material and comprises a first section 24 which includes a pair of spaced parallel prongs 25a and 25b. The prongs are integrally connected at one end by a web 26, the free ends thereof being adapted to be inserted through slot 16 and intermediate the panels 17 and 18. The prongs are bowed in one direction so that when the element 23 is positioned within the frame member 11, the prongs 25a and 25b will become flexed in an unbowed direction thereby placing the panels 17 and 18 under tension and causing them to be urged in opposite directions against the front and back sections 12 and 13, respectively. Element 23 includes a second section 27 which is in the form of a transversely extending flange. The ends 28 of the flange 27 extend sidewise and are curved to conform to the contour of the side of the frame member. The flange 27, when the element 23 is positioned within the frame member 11, is adapted to completely cover over the elongated slot 16 so as to prevent any light rays from passing through said slot. The gasket 21, which was heretofore described as being inserted between panel 18 and back section 13, serves the added function of preventing the light rays from passing around the edges of the panel 18 and through aperture 14, instead of through panel 18.

The spacing 29 between the prongs 25a and 25b is substantially the same as the dimension of the narrow side of the section apertures 14. The length of the prongs, in turn, is substantially the same as the dimension of the long side of the apertures 14, as seen more clearly in Figs. 4 and 6.

While the frame member 11, heretofore described, is adapted primarily for use on the protective mask of a welders helmet, it is to be understood of course that the window construction is not to be limited to such type of frame member, but may be used in other types of installations where the problem of shielding out harmful light rays is of paramount importance.

Thus it will be seen that a window construction has "'icc been provided which is of simple, yet sturdy design, is effective in preventing the harmful lightrays'frompass ing therethrough, and is inexpensive to produce.

While a particular emb odimentnof this invention is shown above, it will be. understood, of course, that the invention is not to be limited. thereto, since many modifications may be made, audit .is contemplated, therefor by the appended claims, to cover any such modifications as fall within the true spirit and scope of this invention.

I claim:

l. A window construction comprising a frame member having spaced substantially parallel front and back sections provided with apertures of like configuration, a portion of the periphery of said front and back sections being connected by a continuous side wall, the remaining portion of the periphery being provided with an elongated slot having a greater extent than the corresponding dimension of said apertures, a pair of removable lenses of substantially the same configuration as said section apertures and positioned between said front and back sections and in substantial registration with said section apertures, and a spacer element having a portion bowed upwardly from one end thereof and positioned between said front and back sections and intermediate said lenses and in contact with marginal portions of the latter to effect urging of said lenses, respectively, against adjacent segments of said sections circumjacent the apertures formed therein, and an opaque flange portion extending upwardly from said one end of saidbowed portion, said flange portion conforming substantially to the exposed surface configuration of said slotted periphery portion and overlying and closing off completely said slot when said bowed portion is inserted to its fullest extent through said slotted "periphery.
